Derrick head and derrick device

Abstract

The invention discloses a derrick head and a derrick device and relates to the technical field of engineering machines. The derrick head and the derrick device aim at solving the problem that eccentric force on a derrick is too large when an iron tower component is lifted and ensuring the stability and the construction safety of the overall derrick. According to the main technical scheme, the derrick head comprises a stand column and pulley set supporting frames, the stand column is of a hollow structure and is installed at the upper end of a derrick body, two through holes which are arranged oppositely are formed in the outer wall of the stand column, the connecting line of the two through holes penetrates through the center of the stand column, and the two through holes are formed in the same horizontal plane. The two pulley set supporting frames are installed on the parts, below the through holes, of the outer wall of the stand column, and pulley assembly installation parts are arranged at the tail ends of the pulley set supporting frames. The invention further discloses the derrick device which comprises the derrick body and the derrick head, and the derrick head is arranged at the top end of the derrick body. The derrick head and the derrick device are mainly used for erecting of high-voltage iron towers and the like in the electric transmission line construction, and stability and the construction safety are good.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a pole holding head and a pole holding device. Background technique [0002] In the construction of transmission lines, it is often necessary to erect high-voltage iron towers, etc., and high-voltage iron towers are generally quadrangular iron towers assembled from several steel rods as tower materials. When erecting a high-voltage iron frame, it is necessary to first build the foundation and tower feet on the ground, and then gradually build up the tower material components. When the high-voltage iron tower is erected to a certain height, in order to safely transport each component to the erected height, it is necessary to use a pole The device (that is, the pole) is used as an auxiliary lifting tool. [0003] The existing pole holding devices generally include a pole body and a pole holding head. The main body of the pole body is a structure composed of angle ste...
